Certainly does! Now I know I shouldn't even try my code for a while ;-)

Just searched the archives for both cygwin and cygwin-developers lists,
looking for pthread related discussion. Not much at all, so here're
my two little questions:

1. Anybody actively working on it?
2. Why not try to reuse code from pthreads-win32 project? License
   issue raises its ugly head again (isn't the copyright there owned
   by Cygnus as well?)?

I can cook these up when I get some time.

These are quite tricky to get right ... I have to find out if my minimal
tests failed because of other bugs, or these are not quite working as
expected. I hate debugging threaded code, as much as I hate debugging
startup code.

The trouble are the various missing types and macros. I'm hoping to get
a bit of free time soon, so perhaps I'll take a look.  Now if I can only
find my pthreads reference ...
